I'm afraid our experience has been the same:
1) updating the drivers ferociously does not seem to be helping
2) we are experiencing (1) enscape never starting. If it does eventually start, it takes 10min or so to start. And even if you do successfully launch it, it crashes every other minute.
One of our project managers reached out to me that they haven't been able to use enscape in 3 weeks because no one in the team (7 people!) is able to get it to run long enough to get any productive work done.
I am very very worried about how things have evolved the last year. It seems we've been going backwards instead of forward. For the first time in 6 years, we are looking seriously as the competitors to see if there's anything better out there. That's how bad it's gotten.
I'm available for a conversation with anyone on the developer team who wants to make time for a face to face.
